IOWA, ASSIGNOR TO HIMSELF AND FEED-GAGE FOR PLATEN PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 380,240, dated March 27, 1888.

Application filed August 18, 1887. Serial No. 247.321. (ModeL) .To all whom it may concern:

Be it known that I, FRANK A. BAGLEY, a citizen of the-United States, residing at Cherokee, in the county of Cherokee and State of Iowa, have invented certain new and useful Improvements in Feed-Gages for Platen Printing Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others ro skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in automatic feed-guides for printingpresses, whereby job printing.

presses can be fed by comparatively unskilled hands and the work rapidly and efficiently accomplished with a comparatively small expenditure of time.

The invention consists, substantially, of an adjustable spring-arm attached to the gripper of a platen job-printing press, said spring working on or striking against a metallic plate attached to theplaten-sheet of the press,whereby the sheets of paper are forced to the required gage or point.

In the drawings, Figure 1 is a view in perspective of a portion of a platen, showing my invention applied thereto. Fig. 2 is a side view of the adjustable spring. Fig. 3 is a detail perspective view.

Gorrespondingparts in the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the gripper-arm of a job-printing press, which gripper arm is provided with an approximately U shaped bend or side projection, a, to permit of the proper application of myinvention. To this U-shaped bend or projection of the gripper-arm is adj ustably secured one end of a spring-arm, B, the same being projected between the side arms or straight portions of said bend, as shown. This spring-arm consists of a straight portion, b, which is designed to bear against the gripper-arm, and an outwardly-curved portion, 12, the outer end of which is bent at a direct angle to'said curved portion, forming aflange, b, as shown.

C is a metallic plate designed to be secured to the platen-sheet, and against the smooth surface of this plate strikes the flanged end of 5c .the spring-arm B when in operation. This metallic plate is provided at its corners with teeth or projections b,which extend outwardly and downwardly therefrom, as shown. By

means of these teeth or projections the me- 5 tallic plate 0 is secured in position on the platen sheet, said teeth being designed to enter said platen-sheet, and thus firmlyhold the plate in position.

In practice, when the press is in operation,

the flanged end of the spring-arm B will, as the platen approaches, come in contact with the smooth surface of the plate 0, and said spring being compressed by the action of the; press the edge of the flanged end of said spring; will strike against the edge of the paper and force the same to the required gage or point.

It will thus be seen that if the paper is unevenly placed onthe platen it will be forced to the proper gage by means of the springarm before contact of the type and paper,

thereby properly presenting said paper to receive the type-impression.

My invention is so arranged that it will not interfere with the original offlce of the gripper-arm, which, as before stated, for the purpose of the proper application of my invention, is provided with a bend wherein the spring-arm is secured.

Another feature of my invention is the ad j ustability of the spring-arm, the same being held on the gripper-arm at the desired point, according to the gage previously determined.

I claim as my invention-- 1. As an improvement in feed-gages for printing-presses, the adjustable spring-arm having a flanged end designed to strike the edge of the paper to be printed upon, substantially as shown and described.

7 2. The spring-arm adjustably secured at one end to'a gripper-arm of a printing-press, and having aflanged end, as-shown anddescribed. I

1 3. The combination, with-a gripper-arm of a printing-press, of the spring-arm adjustably secured to said gripper-arm, and having an outwardly curved and flanged portion, substantially as set forth.

4. The combination, with the gripper-arm having a curved and flanged portion, and the having a bend or side proj ecti0n,0f the springmetallic plate secured to the platen-sheet, sub- :0 arm adjustably secured to said gripper-arm stantially as show-n and described. I between the sides of said bend, substantially 5 as shown and described. FRANK BAGLEY' 5. As an improvement in feed-gages for Witnesses: printing-presses, the combination, with the THOS. MOGULLA, gripper-arm, of the adjustable spring-arm R. L. ROBIE.
